Fix resource leak in pthread_create(). Pthread field "pt_lwpctl"
must not be accessed after _lwp_exit() as the kernel may free
it, attach it to another thread and change its "lc_curcpu".
The "pthread__deadqueue" will fill up with pthreads with
an invalid "pt_lwpctl" and allocated stack that never get
reused.
Replace the test "lc_curcpu == LWPCTL_CPU_EXITED" with
test "_lwp_kill(newthread->pt_lid, 0) == -1 && errno == ESRCH"
to make sure this thread has finished its _lwp_exit().

Make sure to allocate enough space for the thread's stack for a guard
even though there shouldn't be one, so that when we run the thread,
it doesn't start with the stack pointer pointing into someone else's
allocation (like malloc) causing stack frames to trash another data

libpthread(3): Fix a marvellous interaction with rtld.
Patch from chs@. Comment explaining the story by me. This patch may
not be optimal -- maybe it would be better in pthread__init, or
better for rtld to call _lwp_unpark after _lwp_park in the contened
case -- but we've tested this version and it's annoying to reproduce,
so let's take this version and worry about testing improvements

libpthread: Move namespacing include to top of .c files.
Stuff like libc's namespace.h, or atomic_op_namespace.h, which does
namespacing tricks like `#define atomic_cas_uint _atomic_cas_uint',
has to go at the top of each .c file. If it goes in the middle, it
might be too late to affect the declarations, and result in compile
errors.
I tripped over this by including <sys/atomic.h> in mips
<machine/lock.h>.
(Maybe we should create a new pthread_namespace.h file for the
purpose, but this'll do for now.)

- Make pthread_condvar and pthread_mutex work on the stack rather than in
pthread_t, so there's less chance of bad things happening if someone calls
(for example) pthread_cond_broadcast() from a signal handler.
- Remove all the deferred waiter handling except for the one case that really
matters which is transferring waiters from condvar -> mutex on wakeup, and
do that by splicing the condvar's waiters onto the mutex.
- Remove the mutex waiters bit as it's another complication that's not
strictly needed.

If _malloc_thread_cleanup is implement, call it from libpthread.
Provide the hook from modern jemalloc to avoid using TSD for the thread
destruction cleanup as it can result in reentrancy crashes if fork is
called from a thread that never called malloc as it will result in a
late malloc from the pre-fork synchronisation handler.

Deal with a couple of problems with threads being awoken early due to
timeouts or cancellation where:
- The restarting thread calls _lwp_exit() before another thread gets around
to waking it with _lwp_unpark(), leading to ESRCH (observed by joerg@).
(I may have removed a similar check mistakenly over the weekend.)
- The restarting thread considers itself gone off the sleep queue but
at the same time another thread is part way through waking it, and hasn't
fully completed that operation yet by setting thread->pt_mutexwait = 0.
I think that could have potentially lead to the list of waiters getting
messed up given the right circumstances.

Change the behavior of pthread_equal()
On error when not aborting, do not return EINVAL as it has a side effect
of being interpreted as matching threads. For invalid threads return
unmatched.
Check pthreads for NULL, before accessing pt_magic field. This avoids
faults on comparision with a NULL pointer.
This behavior is in the scope of UB, but should be easier to deal with
buggy software.

pthread_detach(), pthread_join(): go back to using _lwp_detach() and
_lwp_wait(), rather than doing it all in userspace. There's less to go
wrong. Doesn't seem to be a performance penalty.

pthread_exit(): it looks there there is at least one path through which
a thread can exit with waiters still hanging off it (cancellation when
waiting on a condvar) so deal with all/any crappy failure like that and
make sure there are never any waiters left before exiting. Maybe of help

- Fix a race between the kernel and libpthread, where a new thread can start
life without its self->pt_lid being filled in.
- Fix an error path in _lwp_create(). If the new LID can't be copied out,
then get rid of the new LWP (i.e. either succeed or fail, not both).
- Mark l_dopreempt and l_nopreempt volatile in struct lwp.

Transfer all the keys that were created in the libc stub implementation
to the pthread tsd implementation when the main thread is created.
This corrects a problem where a process created keys before libpthread
was loaded (either from the libc constructor or because libpthread
was dlopened later). This fixes a problem with jemalloc which creates
keys in the constructor.

created via pthread_create. Let the existing attribut accessors do the
right thing. Raise the default guard size for threads to 64KB.

libpthread:
Make PTHREAD_KEYS_MAX dynamically adjustable
NetBSD's PTHREAD_KEYS_MAX is set to 256, which is low compared to
other systems like Linux (1024) or MacOS X (512). As a result some
setups tested on Linux will exhibit problems on NetBSD because of
pthread_keys usage beyond the limit. This happens for instance on
Apache with various module loaded, and in this case no particular
developper can be blamed for going beyond the limit, since several
modules from different sources contribute to the problem.
This patch makes the limit conigurable through the PTHREAD_KEYS_MAX
environement variable. If undefined, the default remains unchanged
(256). In any case, the value cannot be lowered below POSIX-mandated
_POSIX_THREAD_KEYS_MAX (128).
While there:
- use EXIT_FAILURE instead of 1 when calling err(3) in libpthread.
- Reset _POSIX_THREAD_KEYS_MAX to POSIX mandated 128, instead of 256.
Fix previous: Can't use calloc/malloc before we complete initialization
of the thread library, because malloc uses pthread_foo_specific, and it will
end up initializing itself incorrectly.
Thanks rump for not letting us use even mmap during initialization.
libc/jemalloc:
Fix non _REENTRANT build.
Defer using pthread keys until we are threaded.
From Christos, fixes PR port-arm/50087 by allowing malloc calls prior
to libpthread initialization.

Allow for arbitrary MI scheduler implementations.
A concrete result is enabling unpatched libpthread to run on the
rumprun stacks (e.g. Xen and bare metal) with a non-NetBSD scheduler.
Those schedulers hook into the existing _lwp_frobnitz() NetBSD syscall
interfaces (well, "syscall" interfaces in that scenario ;)
More specifically about the change itself:
1) instead of calling _lwp_makecontext() followed by _lwp_create()
and passing the entry point in ucontext_t (MD) through the calls, roll
the calls into pthread__makelwp() and allow alternate implementations
for that MI interface.
2) allow compile-time overriding of __lwp_gettcb_fast() or
__lwp_getprivate_fast, which are inline and leak MD scheduler/thread
details into libpthread
Additionally, two small nits:
I) define LIB=pthread before including mk.conf so that it's possible
to test for LIB==pthread in mk.conf
II) make it possible to leave out pthread_cancelstub.c. This is required
by the current implementation of rumprun-posix (i.e. rumprun on
POSIX hosts) due to symbol collisions. It needs to be fixed properly
some day, but for now allows an almost-correct libpthread to run.
I am sure @justin will be happy to explain the details ;)

Add TLS support infrastructure. For dynamic binaries, ld.elf_so exports
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.
Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.
It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

I've had this patch in my tree for a while and since it only improves
the situation, I decided to commit it. There is an inherent problem
with ASLR and the way the pthread library is using the thread stack.
Our pthread library chooses that stack for each thread strategically
so that it can locate the location of the pthread struct for each
thread by masking the stack pointer and looking just below the red
zone it creates. Unfortunately with ASLR you get many random values
for the initial stack, and there are situations where the masked
stack base ends up below the base of the stack. (this happens on
x86 when the stack base happens to be 0x???02000 for example and
your mask is stackmask is 0xffe00000). To fix this, we detect the
pathological cases (this happens only in the main thread), allocate
more stack, and mprotect it appropriately. Then we stash the main
base and the main struct, so that when we look for the pthread
struct in pthread__id, we can special case the main thread.
Another way to work around the problem is unlimiting stacksize,
but the proper way is to use TLS to find the thread structure and
not to play games with the thread stacks.

This is not currently done (a bug), nor does libpthread use the
threadreg yet. I'm doing this so it the code can be used by the
person working on TLS to verify that their threadreg code is working.

- Make the threadreg code use _lwp_setprivate() instead of MD hooks.
XXX This must not be enabled by default because the LWP private mechanism
is reserved for TLS. It is provided only as a test/demo.
XXX Since ucontext_t does not contain the thread private variable, for a
short time after threads are created their thread specific data is unset.
If a signal arrives during that time we are screwed.
- No longer need pthread__osrev.

PR lib/38741 priority inversion in libpthread breaks apps that use
SCHED_FIFO threads
- Change condvar sync so that we never take the condvar's spinlock without
first holding the caller-provided mutex. Previously, the spinlock was only
taken without the mutex in an error path, but it was enough to trigger the
problem described in the PR.
- Even with this change, applications calling pthread_cond_signal/broadcast
without holding the interlocking mutex are still subject to the problem
described in the PR. POSIX discourages this saying that it leads to
undefined scheduling behaviour, which seems good enough for the time being.
- Elsewhere, use a hash of mutexes instead of per-object spinlocks to
synchronize entry/exit from sleep queues.
- Simplify how sleep queues are maintained.

- Add pthread__getenv() and use instead of getenv(). This is used before

Other changes:
- Cache the spinlock vectors in pthread__st. Internal spinlock operations

- Use pthread__self() internally, not pthread_self().
- Use __attribute__ ((visibility("hidden"))) in some places.

Check in changes to locking behavior.
pthread__sched() now takes a parameter indicating if the run queue is
already locked. Useful in cases where we already hold pthread__runqueue_lock.
pthread__suspend() now requires callers explicitly lock pthread__runqueue_lock
so we avoid issues with locking order regarding pt_statelock.
Adjsut our lock hierarchy. pthread__runqueue_lock is now above
pt_statelock, triggering the above adjustments. Adjust a lot of routines
as a result. Also move pt_siglock way up in the hierarchy, making
pthread__kill() not violate locking. Add a few extra locks to the list.
Adjust a botch in how pthread_join() used pthread-spintrylock().
pthread_cancel() now correctly walks up the locks with thread->pt_sleeplock.
We can't just lock it, as it points to a lock in the top locking rung. So
try locking, and if it fails, unlock and re-lock. Add code to cope with
the target thread not being in the expected state (which was on a
blocked queue) after we get all the locks.
Add comments to describe what's going on in places that I got confused.
Now that pt_statelock is lower in the locking order than
pthread__runqueue_lock, we can explicitly lock a thread's state before
we take it off the run queue. Adjust sched_yield() accordingly and
add some locking calls that were commented out before (as they'd have
been locking violations).
pthread_next(): now that we can lock the state lock while holding the run
queue lock, do so. Set a thread's state to PT_STATE_RUNNING before we
pull it off the run queue. Since we always are going to switch to it,
set pt_vpid and pt_lastlwp while setting the state. pthread_next
callers now _don't_ set these values.
pthread__kill(): grab pthread__runqueue_lock before target->pt_statelock.
If we want to target a thread that is on a blocked queue, do the
pthread_spintrylock() dance. Unlock all three locks we're running around
with, lock target->pt_sleeplock, then re-lock them all. After we lock,
make sure that the thread's still on a blocked queue before proceeding. If
it's not, either exit (if we wanted to wake out of sigtimedwait())
or start it all over. If the thread has gone live, it may have blocked
our signal and it'd be quite weird to get a signal you'd disabled, just
because the signaller had been running before you blocked it.

Work on cleaning up lock ordering. Turns out that there's not too
much to do, other than fixing an issue in join and one I introduced.
Add volumous comment in pthread_int.h describing how I understand the
current locking to work.
pthread_join() considered pt_flaglock to be a higher-priority lock
than pt_join_lock. Life makes more sense if we flip that.
To not make a lot of routines messy, pthread__runqueue_lock has to be
lower in the lock ordering than pt_statelock. Adapt the changes I made
to sched_yield() to this ordering.
There still is a wart regarding setting the state of a thread
we are taking off of the run (or idle) queue. We can't lock
its pt_statelock as we have the runqueue lock held. For now,
go back to what the old code did which was just write over the info.
This isn't that bad as the only things that should be changing
the state of this thread should be run-queue savy. I need to check
this though....

Check in first step towards having pthread_kill() kill a thread running
on another CPU.
This change adds initial support for deferred signal handling. Just before
we go to sleep and while we hold &self->pt_statelock, check to see if we
have any deferred signals (blocked signals) pending. These are signals
that are not masked in our mask and which have been sent to us. We
were running when they came in. Further, since they are being handled
this way, there's a signal handler defined for them.
So unlock, run the signal handler(s), then carry on.
For condition variables, we consider this a spurious wakeup, so we just
return 0, having not unlocked the mutex. We run the handler with
the mutex held. This shouldn't matter, as you aren't supposed to play
with mutexes in signal handlers. :-)
For nanosleep(), we just process signals, then go to sleep.
For all other cases, we are in a loop with some external predicate. So
we process the signal then roll around the loop to see if it still applies.
In sched_yield(), spin until all deferred signals are gone. Since we hold
self->pt_statelock and that lock has to be held before sending a deferred
signal, no new deferred signals will come in until we're asleep.
While here, be more careful about locking while changing pt_state
to PT_STATE_RUNNING. Grab pt_statelock while doing it, and also set
next->pt_vpid to self->pt_vpid holding the same lock. Will make
the test to determine how to deliver a signal work right (since
a thread's vpid will soon matter in the general case). No longer
set next->pt_vpid in pthread__next().

- Get rid of self->pt_mutexhint and use pthread__mutex_owned() instead.
- Update some comments and fix minor bugs. Minor cosmetic changes.
- Replace some spinlocks with mutexes and rwlocks.
- Change the process private semaphores to use mutexes and condition
variables instead of doing the synchronization directly. Spinlocks
are no longer used by the semaphore code.

- Don't take the mutex's spinlock (ptr_interlock) in pthread_cond_wait().
Instead, make the deferred wakeup list a per-thread array and pass down
the lwpid_t's that way.
- In pthread_cond_wait(), take the mutex before dealing with early wakeup.
In this way there should never be contention on the CV's spinlock if
the app follows POSIX rules (there should only be contention on the
user-provided mutex).
- Add a port of the kernel's rwlocks. The rwlock's spinlock is only taken if
there is contention. This is enabled where atomic ops are available. Right
now that is only i386 and amd64 because I don't have other hardware to
test with. It's trivial to add stubs for other architectures as long as
they have compare-and-swap. When we have proper atomic ops the old rwlock
code can be removed.
- Add a new mutex implementation that's similar to the kernel's mutexes, but
uses compare-and-swap to maintain the waiters list, so no spinlocks are
involved. Same caveats apply as for the rwlocks.

Change the signature of _lwp_park() to accept an lwpid_t and second
hint pointer, but do so in a way that remains compatible with older
pthread libraries. This can be used to wake another thread before the
calling thread goes asleep, saving at least one syscall + involuntary
context switch. This turns out to be a fairly large win on the condvar
benchmarks that I have tried.

- Make the number of spins controllable with the env var PTHREAD_NSPINS.
- Reduce the amount of time that libpthread internal spinlocks are held.
- Rely more on the barrier effects of park/unpark to avoid taking spinlocks.
- Simplify the locking around pthreads and the global queues.
- Align per-thread sync data on a 128 byte boundary.
- Offset thread stacks by a small amount to try and reduce cache thrash.

Pullup revs 1.43-1.46 (requested by chs in ticket #926)
In pthread_mutex_lock_slow(), pthread_rwlock_timedrdlock() and sem_wait(),
call pthread__start() if it hasn't already been called. this avoids
an internal assertion from the library if these routines are used
before any threads are created and they need to sleep.

Fix the interaction between sigtimedwait() and pthread_kill(),
both waking up a sleeping thread and avoiding going to sleep if
a signal is already pending. PR#30348
In pthread_kill() and pthread_suspend_np(), return without doing anything
f the target thread is a zombie.
In all the functions that didn't do so already, verify a pthread_t before
dereferencing it (under #ifdef ERRORCHECK, since these checks are not
mandated by the standard).
Starting the pthread library (ie. calling pthread__start()) before
any threads are created turned out to be not such a good idea.
there are stronger requirements on what has to work in a forked child
while a process is still single-threaded. so take all that stuff
back out and fix the problems with single-threaded programs that
are linked with libpthread differently, by checking if the library
has been started and doing completely different stuff if it hasn't been:
- for pthread_rwlock_timedrdlock(), just fail with EDEADLK immediately.
- for sem_wait(), the only thing that can unlock the semaphore is a
signal handler, so use sigsuspend() to wait for a signal.
- for pthread_mutex_lock_slow(), just go into an infinite loop
waiting for signals.
If mlock() fails in pthread_create(), return EAGAIN instead of
failing an assertion.

I also noticed that there's a "sem2" test that has never worked in its
single-threaded form. the problem there is that a signal handler tries
to take a sem_t interlock which is already held when the signal is received.
fix this too, by adding a single-threaded case for sig_trywait() that
blocks signals instead of using the userland interlock.

Pull up revision 1.36 (requested by yamt in ticket #801):
- fix pthread_detach with an already exit'ed thread.
namely, put the thread to deadqueue rather than just leaking it.
- fix a race between pthread_detach/join and pthread_exit,
which also causes dead thread leaks.

enhance MI pthreads code to support hppa:
- statically initialize all global spin locks. on hppa, 0 means
the lock is held, so leaving them with the default value doesn't work.
- compare functions pointers using a function-pointer type rather than
an integral type. on hppa, function pointers may be indirect,
so we need to trigger gcc to emit calls to the function-pointer
canonicalization routines in the millicode.
- on hppa the stack grows up, so handle that using the STACK_* macros.

Lock accesses to pt_flags and pt_cancel.
When disabling cancellation, clear the pt_cancel flag if it was set
and note the cancellation request with PT_FLAG_CS_PENDING. This avoids
a problem where a cancellation request entered but not acted upon before
pthread_setcanclstate(PTHREAD_CANCEL_DISABLE) is called would still be
aceted upon before cancellation was re-enabled.

Implement a bunch of pthread_attr_() functions, which genuinely set and examine
pthread_attr_t objects, although most of the properties being set don't really
affect threads yet:
pthread_attr_{get,set}guardsize()
pthread_attr_{get,set}inheritsched()
pthread_attr_{get,set}scope()
pthread_attr_{get,set}stack()
pthread_attr_setstack{size,addr}()
Remove some useless assertions and error checks in the existing pthread_attr()
routines.
Implement pthread_attr_get_np(), to examine the attributes of an existing
thread. Idea and interface from FreeBSD.
Change PTHREAD_ERRORMODE environment variable to PTHREAD_DIAGASSERT, and
make it behave like libc's LIBC_DIAGASSERT. The way to disable error-checking
and aborting is now "PTHREAD_DIAGASSERT=AEL", rather than
"PTHREAD_ERRORMODE=ignore".

As pointed out recently on comp.programming.threads, POSIX requires
that pthread_detach() and pthread_join() must return ESRCH, not invoke
undefined behavior, even if handed completely nonsensical pthread_t values.
So, search through the list of threads to see if the pthread_t value is
valid.

Many signal improvements:
- Implement sigsuspend()
- Take pending signals that are unblocked in pthread_sigmask().
- Tweak the signal mask passed by sigaction() to permit us to manage
our own thread-specific signal masks.
- Don't try to deliver signals to zombie threads.
- Prevent a race between deciding a thread can take a signal and actually
taking it.
- Don't put threads that are blocked in a syscall on the run queue.
- Add debug logging.

Different way of integrating with libc: Create a vector type for pthread
operations; libc will have a pointer to such a vector. When the pthread
library is loaded, set libc's pointer to a vector of real operations.
This removes the reliance on weak symbol magic, which didn't work
for static binaries, and as an aesthetic side effect, we don't have to
export a bunch of ugly _libc_pthread_* wrappers.

Cancellation support.
This includes implementing pthread_cancel() and pthread_testcancel(),
making pthread_join() and pthread_cond_wait() cancellation points,
introducing new states to distinguish waiting on a sleep queue
from waiting in the kernel, and introducing a locking protocol around
changing a thread's run state.

Use getcontext() instead of _getcontext() before initializing the
new thread state with makecontext(), since the callee-save registers saved
by _getcontext() may not include the registers needed by makecontext().
Unfortunately, this implies a syscall for every new thread creation.
